At least the following matters will be made clear by the description in this specification and the accompanying drawings.
Having a front-rear direction, a left-right direction, and a vertical direction crossing each other, a main body having a urine passage portion through which urine passes, and a tray on which an absorber for absorbing urine passing through the urine passage portion is installed, An animal toilet having an opening for accommodating the tray at a lower end on one side in the front-rear direction of the main body, and a length of the opening in the left-right direction. Is a length longer than the length of the tray, and the bottom of the main body and the bottom of the tray are each grounded in a state where the tray is accommodated in the main body.

  According to such an animal litter box, it is possible to reduce the overall height by being composed of the two members of the main body and the tray, and it is possible to reduce the labor for cleaning and maintenance. In addition, since the tray can be taken in and out without moving the main body, if a space for sliding the tray back and forth is secured, the absorber can be easily replaced. Therefore, the absorber can be easily exchanged even in a narrow space.

  Further, a main body having a front-rear direction, a left-right direction, and a vertical direction intersecting with each other, a main body having a urine passage portion through which urine passes, and a tray on which an absorber for absorbing urine passing through the urine passage portion is installed In the animal toilet having a notch, a cutout portion which is cut obliquely so as to form a predetermined angle with respect to a horizontal plane is provided at a bottom portion on the rear side in the front-rear direction of the main body portion. The animal litter box is characterized in that the main body portion is capable of standing on its own by tilting the notch portion to the ground so as to be inclined by the predetermined angle with respect to the horizontal plane.

  According to such an animal litter box, it is possible to expose the front portion in the front-rear direction of the tray by tilting the main body part to be self-supporting, so that the tray does not need to be largely slid in the front-rear direction. , The absorber can be replaced. Therefore, even in a narrow space, it is possible to easily perform the replacement work of the absorber and the like.

  Further, a main body having a front-rear direction, a left-right direction, and a vertical direction intersecting with each other, a main body having a urine passage portion through which urine passes, and a tray on which an absorber for absorbing urine passing through the urine passage portion is installed. The animal litter box having an animal toilet having a guide portion protruding inward from an outer side in the left-right direction on a wall portion on both sides in the left-right direction of the main body portion, wherein the guide portion is provided on the tray. The animal litter box is characterized in that the tray is slidable in the front-rear direction by slidably contacting both sides in the left-right direction.

  According to such an animal litter box, even in a narrow space, in the operation of taking the tray in and out of the main body, it is possible to prevent the sliding direction of the tray from being inclined. Thereby, in the animal litter box composed of the main body and the tray, the tray can be taken in and out more stably.

  In the animal litter box, the length of the tray in the front-rear direction is shorter than the length of the tray in the left-right direction, and the tray is housed in the main body by sliding in the front-rear direction. Is desirable.

  According to such an animal litter box, the sliding distance of the tray along the short direction (front-rear direction) is smaller than the sliding distance along the longitudinal direction (left-right direction). Can be shortened. Therefore, the space (space) required for the tray accommodating operation is reduced, and even in a narrow space, it is possible to easily perform the replacement work of the absorber and the like.

  In such an animal litter box, it is preferable that the tray has a symmetrical shape in the front-rear direction, and that the tray can be accommodated in the main body part by changing the direction in the front-rear direction.

  According to such an animal litter box, when the tray is housed in the main body, it is not necessary to check the front-rear direction, and problems such as incorrect insertion in the front and rear are less likely to occur. Further, by changing the front-rear direction (left-right direction) of the tray, the user can replace the front-rear direction (left-right direction) of the absorber without touching the absorber. Therefore, the entire area of the absorber can be used efficiently, and the replacement frequency of the absorber can be reduced.

  In such an animal litter box, it is preferable that the tray has handles on both sides in the front-rear direction.

  According to such an animal litter box, when the user lifts or moves the tray in the operation of switching the front and rear of the tray, the user can stably grip the handle portions on both sides in the front-rear direction. Can hold the tray.

  In the animal litter box, it is preferable that a notch for accommodating the handle is provided at a lower end of the main body in the front-rear direction.

  According to such an animal litter box, the tray can be inserted into the main body without causing interference between the side wall on the rear side in the front-rear direction of the main body and the handle of the tray. This makes it possible to arrange the side wall portion and the handle portion so as to overlap in the front-rear direction, and to shorten the length of the animal litter box in the front-rear direction. Therefore, a more compact and space-saving animal litter box can be realized.

  In the animal litter box, it is desirable that the position of the urine passage portion in the vertical direction is higher than the position of the handle portion.

  According to such an animal litter box, when the tray is slid in the front-rear direction, the handle portion and the urine passage portion hardly come into contact with each other in the up-down direction. Therefore, it is possible to prevent the excrement such as urine from adhering to the handle and becoming dirty. In addition, the handle portion is prevented from being caught on the main body portion, and the tray can be smoothly accommodated.

  In such an animal litter box, the tray has a lower surface portion, and the lower surface portion is provided with a pair of convex portions projecting downward in the vertical direction and extending linearly along the front-rear direction. Is desirable.

  According to such an animal litter box, since the convex portion is provided, the contact area between the lower surface portion of the tray and the floor surface is reduced, and when the tray is slid in the front-rear direction, the contact with the floor surface is reduced. Friction can be reduced. Thereby, the sliding movement of the tray becomes smooth, and the accommodation operation of the tray becomes easy. In addition, the movement direction of the tray is easily regulated in the front-rear direction in which the protruding portion extends, so that smoother sliding movement can be realized.

  In such an animal litter box, the tray has a lower surface, and side walls that surround four sides of the lower surface and extend along the front-rear direction and the left-right direction, respectively. It is desirable to have accommodating portions for folding and accommodating at least a part of the absorber at four corners in the left-right direction.

  According to such an animal litter box, a part of the absorber (corner portion) is folded into the accommodation portion, and the absorber is fixed inside the tray. The body can be prevented from protruding outside the tray.

  In this animal litter box, the tray has a plate-like rib projecting upward from the lower surface in the up-down direction, and the side wall has a first side wall and a second side wall that intersect each other. It is preferable that the accommodation portion is a space surrounded by the first side wall portion, the second side wall portion, and the rib.

  According to such an animal litter box, when a part of the absorber is folded into the housing part surrounded by the first side wall part and the second side wall part and the rib, the absorber is bent from the rib as a starting point, The absorber is easily held stably. Therefore, the position of the absorber can be easily fixed, and the absorber can be made hard to protrude outside the tray.

  In this animal litter box, it is preferable that the rib has a notch at the center in the width direction of the rib, the upper end of the rib being cut off.

  According to such an animal litter box, when the absorber is folded into the accommodation portion, the manner in which the absorber is bent is different between a portion where the notch is formed and a portion where the notch is not formed. it can. Thereby, the bending of the absorber becomes complicated, and it becomes difficult for the absorber to separate from the storage portion. Therefore, the displacement of the absorber can be made harder to occur.

  In this animal litter box, the ceiling has a top portion that straddles an upper end of the first side wall portion and an upper end of the second side wall portion, and the accommodation portion includes the first side wall portion and the second side wall portion. And a space surrounded by the ribs and the ceiling.

  According to such an animal litter box, when the absorber is folded into the accommodation portion, the upward movement of the absorber is restricted by the ceiling, so that the absorber may be detached from the tray. It is easy to be suppressed. Therefore, the displacement of the absorber can be made harder to occur.

  In the animal litter box, the tray has a tubular through tube penetrating the lower surface portion and protruding upward in the up-down direction, and the housing portion is a space inside the through tube. It is desirable.

  According to such an animal litter box, when a part of the absorber is pushed into the inside of the tube of the penetration tube, the position of the absorber is easily fixed, and it is possible to prevent a displacement from occurring.

  In this animal litter box, it is desirable that the height of both sides of the tray in the left-right direction is higher than the height of the center of the tray.

  According to such an animal litter box, the height of the tray is kept as low as possible by lowering the height at the center in the left-right direction, while the height at both ends in the left-right direction is increased, thereby fixing the absorber. It is easy to form a large space (accommodating portion) for the operation. Thus, while keeping the overall height of the animal litter box low, it is possible to suppress the displacement of the absorbent sheet placed on the tray and to effectively suppress excretion leakage.

  In the animal litter box, it is preferable that a regulation portion for regulating the movement of the tray in the front-rear direction is provided on a front side wall in the front-rear direction.

  According to such an animal litter box, the front side wall of the tray interferes with the regulating portion, so that the movement of the tray in the front-rear direction is suppressed. Thus, it is possible to prevent the tray from being detached from the main body due to an erroneous operation or the like after the tray is accommodated in the main body.

  In the animal litter box, it is preferable that at least a part of the bottom of the main body has a reversing portion that is reversed from one side in the front-rear direction or the left-right direction to the other side.

  According to such an animal litter box, by providing the reversing portion, the area where the bottom of the main body portion contacts the floor or the like is increased, and the contact stability is improved. In addition, since the bending strength in the left-right direction (or the front-back direction) is increased in the portion of the main body portion (side wall portion) where the inversion portion is provided, the main body portion (side wall portion) may be bent or bent. Can be suppressed.

=== First Embodiment ===
<Overall configuration>
As an example of the animal litter box according to the first embodiment, an animal litter box 1 will be described. FIG. 1 is a schematic perspective view of the animal litter box 1. Further, in the following description, as shown in FIG. 1, three directions orthogonal to each other, ie, “front-back direction”, “left-right direction”, and “up-down direction” are defined. The front-rear direction is a direction along the lateral direction of the animal litter box 1 in the present embodiment, and a side where an animal entrance / exit (an entrance notch 18 described later) is provided is a front side. The left-right direction is a direction along the longitudinal direction of the animal litter box 1. The vertical direction is a direction along the vertical direction. FIG. 2 is a plan view (three views) of the animal litter box 1 as viewed from the up-down direction, the front-rear direction, and the left-right direction. FIG. 3 is a cross-sectional view showing an AA cross section and a BB cross section of FIG.

  The animal litter box 1 has a main body 10 for receiving animal excrement, and a tray 20 accommodated in the main body 10 and provided with an absorbent sheet (described later) for absorbing urine and the like.

(Main body 10)
The main body 10 has a lower surface 11 and a side wall 15 surrounding the lower surface 11, and is a box-shaped member having an upper opening. Excretion in the state of riding. As shown in FIG. 3, the lower surface 11 of the main body 10 is inclined in a mortar shape from the outside in the left-right direction (and the front-back direction) to the inside (center side). A urine passage portion 12 is provided in the lower portion 11 where the position in the vertical direction is the lowest, to pass urine and the like excreted by the animal from the upper side to the lower side in the vertical direction. The urine passing portion 12 has a plurality of holes 12s penetrating in the vertical direction, and excreted urine moves from the upper side to the lower side (toward the tray 20) of the main body 10 through the holes 12s. I do.

  When using the animal litter box 1, an excrement disposal material (not shown), which is a particulate matter such as cat litter, is installed so as to cover the urine passage section 12 (lower surface section 11). Excrete on the excrement disposal material. The excrement disposal material used for the animal litter box 1 is a granular substance having a porous structure, such as zeolite or silica gel, which absorbs ammonia components and deodorizes by contacting urine excreted by animals. It has an effect and an effect of adsorbing the odor of ammonia trapped from the sheet. It also has the effect of removing moisture. In order to prevent each particle of the excrement disposal material from falling down from the hole 12 s of the urine passage section 12, the hole 12 s has a shape and size which allow the urine to pass therethrough and not pass the excrement disposal material. Is desirable. For example, in the animal litter box 1 of the present embodiment, as shown in FIG. 2, the urine passage section 12 is formed by providing a plurality of slit-shaped holes 12s that are long in the left-right direction.

  The side wall portion 15 includes a front side wall portion 15f disposed on the front side in the front and rear direction, a rear side wall portion 15b disposed on the rear side in the front and rear direction, a right side wall portion 15r disposed on the right side in the left and right direction, and a left side in the left and right direction. And a left side wall portion 15l disposed at the left side.

  The side wall portion 15 has a folded portion 16 that is folded downward in the vertical direction and outward in the front-rear direction (or the left-right direction) at the upper end 15u located above the lower surface portion 11 in the vertical direction. (See FIG. 2). The user can easily lift or move the main body 10 by hooking his / her finger on the folded portion 16. In addition, since the folded portion 16 is provided, the edge of the upper end 15u of the side wall 15 is prevented from sharply rising upward. Thereby, when an animal such as a kitten enters or exits the animal litter box 1, it is suppressed that the leg or the body is damaged due to contact with the upper end 15 u.

  In addition, the side wall portion 15 is grounded at a lower end 15d located below the lower surface portion 11 in a vertical direction with a plane (for example, a floor or a table) on which the animal litter box 1 is placed. In other words, the lower end 15d of the side wall 15 is the lowermost part of the main body 10 in the vertical direction. Hereinafter, the lower end 15 d of the side wall 15 is also referred to as a “bottom” of the main body 10.

  In the side wall part 15, the front side wall part 15f is provided with an inlet notch part 18 in which at least a part of the upper end 15u is cut out in a vertical direction below. The front side wall portion 15f has a height in the vertical direction lower than the other three side wall portions 15b, 15l, and 15r in a region where the inlet cutout portion 18 is provided. Therefore, when an animal such as a kitten excretes, the cutout 18 forms a side wall in the animal litter box 1 (main body 10) (ie, above the urine passage section 12 (lower surface section 11)). (The area surrounded by the section 15). That is, the entrance notch 18 is a part that functions as an entrance of the animal litter box 1.

  An opening 19 for accommodating the tray 20 is provided at the lower end of the front side wall 15f. The length (opening width) W19 of the opening 19 in the left-right direction is longer than the maximum value of the length (width) W20 of the tray 20 in the left-right direction.

(Tray 20)
FIG. 4 is a schematic perspective view of the tray 20. The “front-back direction”, “left-right direction”, and “up-down direction” in FIG. 4 are the same directions as the “front-back direction”, “left-right direction”, and “up-down direction” in FIG. 1, respectively. FIG. 5 is a plan view when the tray 20 is viewed from the upper and lower sides in the up-down direction, the front-rear direction, and the left-right direction.

  The tray 20 has a lower surface portion 21 and a side wall portion 25 surrounding the periphery of the lower surface portion 21, and has a shallow bottom on which an absorber (for example, an absorption sheet 200 described later) that absorbs excreted urine and the like is installed. It is a flat box-shaped container. The side wall portion 25 includes a front side wall portion 25f on the front side in the front and rear direction, a rear side wall portion 25b on the rear side in the front and rear direction, a right side wall portion 25r on the right side in the left and right direction, and a left side wall portion 25l on the left side in the left and right direction. I have.

  As shown in FIG. 5, the tray 20 of the present embodiment is formed in a substantially rectangular shape symmetrical in the front-rear direction. A front handle portion 26f and a rear handle portion 26b are provided at both ends in the front-rear direction, that is, at the front side wall portion 25f and the rear side wall portion 25b, respectively. When storing the tray 20 in the main body 10, the tray 20 can be moved in and out of the main body 10 by sliding the tray 20 in the front-rear direction by gripping and operating the handle 26. it can.

  On the back surface of the lower surface portion 21 (the lower surface in the vertical direction), a convex portion 27 protruding downward in the vertical direction is provided. As shown in FIG. 5, the protrusions 27 are formed in a straight line along the front-rear direction, and are provided in a pair on both sides in the left-right direction. Then, the tip (the lower end in the vertical direction) of the convex portion 27 is grounded to a plane (for example, a floor or a table) on which the animal litter box 1 is placed. That is, the tip of the convex portion 27 is a portion located at the lowest position of the tray 20 in the vertical direction. Hereinafter, the tip of the projection 27 is also referred to as the “bottom” of the tray 20.

  At four corners of the tray 20 in the front-rear direction and the left-right direction, sheet storage units 28 for fixing the absorbent sheet 200 to the tray 20 are provided. The sheet storage unit 28 will be described later.

  The absorbent sheet 200 installed inside the tray 20 is a liquid absorbent sheet member that absorbs urine excreted by an animal such as a cat, and is formed of a liquid absorbent material such as pulp fiber or a highly absorbent polymer. Further, an antibacterial agent may be included in the absorption sheet 200 to prevent germs from propagating, or microcapsules may be included to generate fragrance. When the animal litter box 1 is used, the tray 20 on which the absorbent sheet 200 is installed is housed in the main body 10 through the opening 19, so that the absorbent sheet 200 is placed below the urine passage section 12 in the vertical direction. Be placed. The excrement excreted by an animal such as a cat in the main body 10 passes through the urine passage section 12, moves downward (falls), and is absorbed by the absorbent sheet 200.

  In the present embodiment, the main body 10 and the tray 20 are each formed of a polyolefin-based thermoplastic resin such as polyethylene, polypropylene, and polyethylene terephthalate. However, the material forming each member is not limited to this, and may be, for example, another resin, wood, a metal material such as a stainless steel plate or an aluminum plate, or another member.

<Replacement of absorption sheet 200>
As described above, when the animal litter box 1 is used, the tray 20 on which the absorbent sheet 200 is arranged is stored in the main body 10, and when the absorbent sheet 200 is replaced, the tray 20 is inserted through the opening 19 provided in the main body 10. The tray 20 is put in and out.

  Since the animal litter box 1 of the present embodiment is composed of the main body 10 and the tray 20, the overall height is lower than that of a conventional animal litter box composed of three or more members. It is hard to get high. When the animal litter box 1 is placed on a horizontal surface such as a floor or a table, the bottom of the main body 10 (lower end 15d) and the bottom of the tray 20 (convex portion 27) are grounded. That is, the main body 10 is not provided with a portion for accommodating the bottom of the tray 20. For example, in Patent Literature 1, the bottom of the outer container is disposed below the bottom of the tray when the tray is housed inside the outer container. However, in the animal litter box 1, the bottom of the tray 20 is located below the bottom of the tray 20. Does not have a main body. Therefore, the height of the main body 10 can be reduced accordingly, and the overall height of the animal litter box 1 can be suppressed low. This makes it easier for kittens and animals with short legs to enter and exit the animal litter box 1.

  When replacing the absorbent sheet 200, the tray 20 can be easily taken in and out by sliding the tray 20 in the front-rear direction with respect to the main body 10. In the present embodiment, the maximum value of the length W20 of the tray 20 in the left-right direction is smaller than the length W19 of the opening 19 in the left-right direction. Therefore, when the tray 20 is slid along the front-rear direction in the accommodation operation of the tray 20, the side walls 25 on both sides in the left-right direction of the tray 20 hardly interfere with the opening 19 of the main body 10. That is, since the tray 20 is hardly caught by the opening 19, the operation of taking the tray 20 in and out of the main body 10 can be smoothly performed.

  Many conventional animal litter boxes are composed of three or more members (for example, an upper container, a lower container, and a tray), so that the height tends to be high, and cleaning and maintenance are troublesome. . In addition, since the number of members is large, the whole is likely to be large, and it is difficult to install an animal toilet in the cage when breeding kittens and the like in the cage. In addition, it is difficult to replace the absorbent sheet in a narrow space such as the cage, take out the entire animal litter out of the cage, replace the absorbent sheet, and put the whole animal litter in the cage again. The burden on the user was heavy, such as the need to return it, and it was not suitable for cage keeping.

  On the other hand, the animal litter box 1 of the present embodiment has a two-member configuration, so that the overall height can be suppressed, and the labor for cleaning and maintenance can be reduced. When performing the replacement work of the absorbent sheet 200, the tray 20 can be taken in and out without moving the main body 10. That is, if a space for sliding the tray 20 back and forth is ensured, the replacement of the absorbent sheet 200 can be easily performed. Therefore, it is easy to replace or clean the absorbent sheet 200 in a narrow space, which is suitable when kittens and the like are bred in a cage.

  Further, in the animal litter box 1 of the present embodiment, as shown in FIGS. 2 and 5, the length in the left-right direction is longer than the length in the front-rear direction of the main body 10 and the tray 20. Therefore, when the tray 20 is taken in and out of the main body 10, the tray 20 is slid along the short direction (front-back direction), compared with the case where the tray 20 is slid along the long direction (left-right direction). The moving distance of the tray 20 can be shortened. Accordingly, the space (space) required for taking the tray 20 in and out is reduced, and the tray 20 can be easily taken in and out even in a narrow space such as in a cage, and work such as replacement of the absorbent sheet 200 is performed more. It will be easier.

  The tray 20 has a symmetrical shape in the front-rear direction, and can be accommodated in the main body 10 with the front-rear direction switched. That is, when the tray 20 is accommodated in the main body 20, it is not necessary to confirm the front-back direction, and problems such as incorrect insertion in the front-rear direction hardly occur. Therefore, the user can store the tray 20 in the main body 10 without worrying about the front-rear direction of the tray 20 (which is the front side and which is the rear side), so that the tray 20 can be stored without stress. be able to.

  Furthermore, since the tray 20 can be used by changing its front-rear direction, the absorbent sheet 200 can be used efficiently efficiently. Generally, animals such as cats have a habit of excreting at a fixed position in the toilet when excreting in an animal litter box. For example, in the case of a cat having a habit of excreting in the right region in the left-right direction, urine and the like are intensively absorbed in the right region of the absorbent sheet 200, so that only the right region of the absorbent sheet 200 is exposed. It is easy to reach the absorption limit early. In such a case, the entire area of the absorbent sheet 200 can be used evenly by changing the arrangement of the absorbent sheet 200 from side to side and rearranging the area arranged on the left side to the right side.

  Specifically, after pulling out the tray 20 from the main body 10, the tray 20 on which the absorbent sheet 200 is arranged is replaced in the front-back direction (that is, the left-right direction), and is stored in the main body 10 again. In this way, the user can change the direction of the absorbent sheet 200 (tray 20) without touching the absorbent sheet 200, and use the absorbent sheet 200 efficiently, and reduce the frequency of replacement of the absorbent sheet 200. can do. Absorbent sheets used for animal toilets are generally used continuously for one week or more, but the frequency of replacement can be reduced simply by changing the direction of the absorbent sheet 200, thereby further reducing the burden on the user. can do.

  In this embodiment, the handle portions 26f and 26b are provided on both sides of the tray 20 in the front-rear direction. Therefore, in the operation of exchanging the front and rear of the tray 20, the user can grab one of the handle portions 26f and 26b provided on the front and rear and put the tray 20 in and out. Thereby, good operability can be maintained even in a narrow space such as in a cage. Further, when the user needs to lift or move the tray 20, it is possible to stably hold the tray 20 by grasping the handle portions 26f, 26b on both sides in the front-rear direction with each hand. .

  The rear side wall portion 15b of the main body portion 10 is provided with a rear notch portion 15bc in which a region of a predetermined height is cut out from a lower end in the vertical direction at a central portion in the horizontal direction (FIG. 3). The rear notch 15bc suppresses interference between the handle 26 provided on the rear side of the tray 20 and the rear side wall 15b of the main body 10 in a state where the tray 20 is housed in the main body 10. It is provided in order to. In other words, the rear notch 15bc is provided to accommodate the handle 26 of the tray 20.

  If the rear side notch portion 15bc is not provided in the rear side wall portion 15b, the rear handle portion 26 is caught by the rear side wall portion 15b when the tray 20 is accommodated in the main body portion 10. Therefore, the tray 20 cannot be inserted to the back of the main body 10 (rear side in the front-rear direction). Alternatively, the length of the main body 10 in the front-rear direction increases, and the shape becomes unsuitable for space-saving use of a cage or the like. On the other hand, in the present embodiment, as shown in the AA cross section of FIG. 3, the provision of the rear notch portion 15bc prevents the handle portion 26 from interfering with the rear side wall portion 15b. The tray 20 can be inserted up to the back (rear side) in the front-rear direction of the main body unit 10 without any need. Therefore, since the rear side wall portion 15b and the handle portion 26 can be arranged at positions overlapping in the front-back direction, the length in the front-back direction of the animal litter box 1 (main body portion 10) can be reduced. It becomes possible. Thereby, the compact and space-saving animal litter box 1 can be realized.

  Further, the tray 20 is grounded by a convex portion 27 provided on the back surface side of the lower surface portion 21. As shown in FIG. 5, the protrusion 27 is formed in a straight line along the front-rear direction. Since the protrusion 27 has a small width in the left-right direction and a small contact area with a floor or the like, the friction between the protrusion 27 and the floor can be reduced when the tray 20 is slid in the front-rear direction. . Thereby, the sliding movement of the tray 20 in the front-rear direction becomes smooth, and the user can put the tray 20 in and out of the main body 10 with a small force. In addition, since the protrusion 27 functions as a skate blade, the movement direction of the tray 20 is easily restricted to the direction in which the protrusion 27 extends. That is, the tray 20 can easily move in the front-rear direction, and smoother sliding movement can be easily realized. However, the convex portion 27 is not an essential component of the tray 20, and may be a configuration in which the convex portion 27 is not provided on the lower surface portion 21.

  In the animal litter box 1, when the absorbent sheet 200 disposed inside the tray 20 has a slightly larger area than the lower surface 21 of the tray 20 in order to suppress leakage of excrement. There are many. When the absorbent sheet 200 having a larger area than the lower surface portion 21 is used, the absorbent sheet 200 is prevented from being displaced inside the tray 20 or not protruding outside the tray 20. It is necessary to fix 200 inside the tray 20 firmly. In the present embodiment, the four corners of the tray 20 in the front-rear direction and the left-right direction (front right, front left, rear right, rear left) accommodate the corners of the rectangular absorbent sheet 200 to accommodate the tray 20. A sheet accommodating portion 28 for fixing the absorbing sheet 200 is provided inside.

  FIG. 6 is a diagram illustrating the sheet storage unit 28. 6A is a perspective view illustrating a portion (left rear corner) of a region K in FIG. 5, and FIG. 6B is a schematic cross-sectional view illustrating an LL cross section in FIG. 5. In the example of FIG. 6A, a plate-like rib 281 protruding upward from the lower surface 21 of the tray 20 and a rear side wall 25 b of the side wall 25 of the tray 20 that intersect with each other (corresponding to “first side wall”). Further, a space surrounded by the left side wall 251 (corresponding to the “second side wall”) and the lower surface 21 forms a sheet storage unit 28.

  When the absorbent sheet 200 is placed on the tray 20, the left rear corner of the absorbent sheet 200 is folded into the sheet storage section 28 as shown in FIG. 6B. Similarly, the other three corners (the front left side, the rear right side, and the front right side) also include the sheet accommodating portion 28 which is a space surrounded by the rib 281 and the side wall portion 25 (the first side wall portion and the second side wall portion). Then, the corners of the absorbent sheet 200 are folded. At this time, the absorbent sheet 200 is bent starting from the rib 281 protruding upward in the vertical direction, so that the absorbent sheet 200 can be easily held stably. In this way, it is possible to arrange the absorbent sheet 200 such that the absorbent sheet 200 does not protrude outside the tray 20 while fixing the position of the absorbent sheet 200. Note that the rib 281 may be in contact with the side wall 25 or may be apart therefrom. That is, the rib 281 may be formed integrally with the side wall 25 or may be formed independently of the side wall 25.

  FIG. 7 is a diagram illustrating a first modification of the sheet storage unit 28. 7A and 7B correspond to FIGS. 6A and 6B, respectively. In the first modified example, a plate-like rib 282 protruding upward from the lower surface 21 of the tray 20 is provided. Further, as shown in FIG. Has a notch 282c cut out in a V-shape. Other configurations are substantially the same as those of the sheet storage unit 28 described with reference to FIG. That is, the sheet accommodating portion 28 is formed by a space surrounded by the rib 282, the rear side wall portion 25b, and the left side wall portion 25l. The rib 282 may be in contact with the side wall 25 or may be apart therefrom.

  In the first modified example, when the absorbent sheet 200 is folded into the sheet accommodating portion 28, a part where the notch 282c is formed is different from a part where the notch 282c is not formed in a manner of bending the absorbent sheet 200. Specifically, in the portion where the notch 282c is provided, the absorbing sheet 200 is bent slightly as shown in FIG. 7B, and in the portion where the notch 282c is not provided, the absorbing sheet 200 is largely bent as in FIG. 6B. Thereby, the way of bending the absorbent sheet 200 becomes complicated, and it becomes difficult for the absorbent sheet 200 to be separated from the sheet accommodating portion 28 which is a space surrounded by the rib 282 and the side wall portion 25. That is, the absorption sheet 200 is easily fixed, and the displacement can be made harder to occur.

  FIG. 8 is a diagram illustrating a second modification of the sheet storage unit 28. 8A and 8B correspond to FIGS. 6A and 6B, respectively. In the second modified example, a plate-shaped rib 283 projecting upward from the lower surface 21 of the tray 20 is provided in the same manner as described with reference to FIG. 6, and a space surrounded by the rib 283 and the side wall 25. Ceiling portion 284 is provided so as to cover a part of. In the example of FIG. 8A, the ceiling 284 is arranged so as to straddle the upper end of the rear side wall 25b (first side wall) of the tray 20 and the upper end of the left side wall 251 (second side wall). The space surrounded by the side wall portion 25 and the ceiling portion 284 becomes the sheet storage portion 28. The rib 283 may be in contact with the side wall 25 or may be apart therefrom. Moreover, the rib 283 may not be provided, and only the ceiling 284 may be provided.

  When the absorbent sheet 200 is folded into the sheet accommodating portion 28 which is such a space, since the upward movement of the absorbent sheet 200 is restricted by the ceiling portion 284, the absorbent sheet 200 is detached from the tray 20. Is easily suppressed. Therefore, the absorbing sheet 200 is easily fixed, and the displacement can be made harder to occur.

  FIG. 9 is a diagram illustrating a third modification of the sheet storage unit 28. 9A and 9B correspond to FIGS. 6A and 6B, respectively. In the third modified example, as shown in FIG. 9A, a cylindrical through pipe 285 that penetrates the lower surface 21 of the tray 20 and protrudes upward in the up-down direction is provided. Then, a sheet storage portion 28 is formed inside the through tube 285. Note that the projecting height h285 of the sheet storage unit 28 (through tube 285) in the third modified example is larger (longer) than at least the thickness of the tray 20 (for example, the thickness t21 of the lower surface 21).

  When the absorbent sheet 200 is set on the tray 20 in the third modification, the corners of the absorbent sheet 200 are pushed into the tube of the through tube 285 as shown in FIG. 9B. Thereby, the position of the absorbent sheet 200 is easily fixed, and it is possible to prevent the displacement from occurring. Note that, by making the projecting height h285 of the through tube 285 larger than the thickness t21 of the tray 20, the absorbing sheet 200 may fall out of the tube of the through tube 285, or the absorbing sheet 200 may be larger than the through tube 285. It can be easily suppressed to protrude to the lower side (below the lower surface portion 21 of the tray 20).

  Further, it is desirable that the height of both sides of the tray 20 in the left-right direction (the longitudinal direction of the tray 20) be higher than the height of the central portion. In FIG. 5, when the tray 20 is viewed from the front-back direction, the height h25s at both ends in the left-right direction is higher than the height h25c at the center part in the left-right direction (h25s> h25c). Since the animal litter box 1 is assumed to be used by kittens and short animals, it is necessary to reduce the overall height as much as possible. Therefore, it is desirable that the height of the tray 20 be as low as possible, and the height h25c at the center in the left-right direction is reduced. On the other hand, at both ends of the tray 20 in the left-right direction, since it is necessary to provide the sheet accommodating portions 28 and fix the absorbent sheet 200 as described above, the height is set so that a space of a certain size can be formed. The height h25s is higher than the height h25c. Thus, while keeping the overall height of the animal litter box 1 low, the displacement of the absorbent sheet 200 arranged on the tray 20 can be suppressed, and leakage of excrement can be effectively suppressed.

  In the present embodiment, also in the inside of the tray 20, the height at both ends in the left-right direction is higher than the height at the center portion in the left-right direction. That is, since the ribs 281 and the like protruding upward from the lower surface 21 are provided at both ends in the left-right direction of the tray 20, the height is higher than the lower surface 21. Therefore, when the absorbent sheet 200 is disposed inside the tray 20, the height of the absorbent sheet 200 at both ends in the left-right direction is higher than the height of the absorbent sheet 200 at the center part in the left-right direction. This facilitates the movement of urine and the like absorbed by the absorbent sheet 200 from both ends in the left-right direction to the center, and suppresses the leakage of urine and the like to the outside of the tray 20.

  When the tray 20 is accommodated in the main body 10, the lowermost position of the lower surface 11 of the main body 10 in the vertical direction is above the highest position of the handle 26 of the tray 20 in the vertical direction. That is, in the up-down direction, the height of the urine passage section 12 is higher than the height of the handle section 26. In the AA sectional view of FIG. 3, the height h12 of the urine passage section 12 in the vertical direction is higher than the height h26 of the handle section 26 in the vertical direction (h12> height h26).

  With such a configuration, when the tray 20 is slid in the front-rear direction, the handle portion 26 and the urine passage portion 12 (the main body portion 10) do not easily come into contact with each other in the up-down direction. Therefore, it is possible to prevent excrement such as urine from adhering to the handle portion 26 and becoming dirty during the operation of storing the tray 20. Further, when the tray 20 is slid, the handle portion 26 is prevented from being caught on the urine passage portion 12 (the main body portion 10), and the accommodation operation of the tray 20 can be performed smoothly. In the present embodiment, the height h26 of the handle 26 is substantially the same as the height h25c at the center in the left-right direction of the tray 20 (see FIG. 5). Therefore, in the animal litter box 1, the side walls 25 f and 25 b of the tray 20 are unlikely to come into contact with the urine passage section 12 in the operation of accommodating the tray 20. That is, it is difficult for the entire tray 20 to come into contact with the urine passage section 12.

  Further, in order to prevent the tray 20 from coming off the main body 10 due to an erroneous operation or the like after the tray 20 is accommodated in the main body 10, the front side wall 15 f of the main body 10 is provided with a front-rear direction of the tray 20. A slide regulating unit 30 for regulating movement may be provided. FIG. 10 is a diagram illustrating an example of the slide regulating unit 30. In the example of FIG. 10, a plate-shaped slide regulating portion 30 (indicated by a hatched portion in FIG. 10) is provided along the edge of the opening 19 of the front side wall portion 15f. In at least a part of the area, the height h30 of the slide restricting portion 30 is lower than the height h25c of the tray 20 at the center in the left-right direction. That is, the slide regulating portion 30 is provided so as to overlap at least a part of the tray 20 (the front side wall portion 25f) in the vertical direction. In FIG. 10, the slide restricting portion 30 is provided as a separate member from the front side wall portion 15f, but the slide restricting portion 30 and the front side wall portion 15f may be the same member. That is, a part of the front side wall portion 15f may constitute the slide regulating portion 30.

  With such a configuration, when the tray 20 is slid in the front-rear direction, the front side wall portion 25f of the tray 20 interferes with the slide restricting portion 30, and the movement of the tray 20 in the front-rear direction is suppressed. Therefore, the tray 20 accommodated in the main body 10 can be prevented from coming off the main body 10 due to an erroneous operation or the like. When the main body 10 is provided with the slide restricting portion 30, the user lifts the front side of the main body 10 slightly upward during the storage operation of the tray 20 so that the tray 20 and the slide restricting portion 30 The tray 20 may be slid in a state in which the tray 20 does not interfere.

  In addition, in the main body 10, a reversing portion 17 is provided in which the lower end 15 d of the side wall 15 (that is, the bottom of the main body 10) is inverted from one side in the front-rear direction to the other side or from one side in the left-right direction to the other side. Have been. FIG. 11 is a plan view when the main body 10 is viewed from below in the vertical direction. As shown in the partially enlarged view of FIG. 11, in the present embodiment, at the front end portions in the front-rear direction of the left and right side wall portions 15l, 15r, the bottom portions of the side wall portions 15l, 15r are moved from the front side in the front-rear direction to the rear side. An inverted portion 17 is provided on the side. By providing the reversing part 17, the area where the bottom of the side wall parts 15l, 15r is in contact with a plane such as a floor in the left-right direction is increased, and the grounding stability of the side wall parts 15l, 15r is improved. Further, since the bending strength of the side walls 15l, 15r themselves in the left-right direction is increased in the portion where the reversing portion 17 is provided, it is possible to suppress the side walls 15l, 15r from bending or bending.

  Although FIG. 11 illustrates an example in which the reversing portions 17 are provided at the front ends of the left and right side walls 15l and 15r, the reversing portions 17 may be provided in other portions of the side wall portions 15. . For example, at a boundary portion between the rear side wall portion 15b and the rear side cutout portion 15bc, a part of the rear side wall portion 15b is formed by reversing from one side in the left-right direction to the other side, thereby forming the reversing portion 17. May be.

=== Second Embodiment ===
In the second embodiment, a description will be given of the animal litter box 2 in which a part of the side wall 15 is cut off at a rear end in the front-rear direction of the main body 10 and a lower end in the vertical direction.

  12A and 12B are views showing the state when the animal litter box 2 is viewed from the left and right directions. The animal litter box 2 has a notch 40 in which the bottom of the main body 10 is cut obliquely so as to form a predetermined angle with respect to a horizontal plane such as a floor. The configuration of the animal litter box 2 is substantially the same as the configuration of the animal litter box 1 of the first embodiment except that the cutout portion 40 is formed in the main body portion 10, and thus the description thereof is omitted.

  As shown in FIG. 12A, in the animal litter box 2, the side wall portion 15 (the left and right side wall portions 15 l and 15 r and the rear side wall portion 15 b) of the main body portion 10 has a rear end portion in the front-rear direction and a vertical direction. At the lower end in the direction, a cutout portion 40 is formed which is cutout so as to form a predetermined angle θ40 with the horizontal plane. Note that the angle formed by the horizontal plane and the notch 40 is the smaller of the angles formed by the intersection of the horizontal direction and the inclination direction of the notch 40 (that is, less than 90 degrees). Small angle).

  As shown in FIG. 12B, the main body 10 of the animal litter box 2 can be self-supported obliquely by grounding the notch 40. Specifically, in a state where the front-back direction of the main body 10 is inclined by an angle θ40 with respect to a horizontal plane, the main body 10 can be self-standing. If such an animal litter box 2 is used, even when an animal such as a kitten is bred in a cage, the tray 20 is slid and moved when exchanging the absorbent sheet 200 in the cage. The distance can be shortened. For example, the main body 10 is tilted obliquely (in the direction of clockwise rotation in FIG. 12B) as shown in FIG. 12B so as to be free-standing, so that the front side of the tray 20 in the front-rear direction is exposed. The absorbent sheet 200 can be easily exchanged without having to slide the absorbent sheet 200 largely in the direction. Therefore, even in a narrow space such as the inside of a cage, it is possible to easily perform the operation of replacing the absorbent sheet 200 and the like.

=== Third Embodiment ===
In the third embodiment, a description will be given of the animal litter box 3 in which a guide portion 50 for guiding the tray 20 to slide in the front-rear direction is provided at the lower end portions of the side wall portions 15r and 151 on both sides in the left-right direction of the main body portion 10.

  FIG. 13 is a schematic cross-sectional view of the animal litter box 3 when viewed from the front side in the front-rear direction. In the animal litter box 3, a pair of guide portions 50r and 50l projecting inward from the outside in the left-right direction are provided at lower end portions of the side wall portions 15r and 15l. The inner ends 50re and 50le in the left-right direction of the guide portion 50 are formed in a linear shape along the front-rear direction, and when the tray 20 is housed in the main body portion 10, the side wall portions 25r on both sides in the left-right direction of the tray 20. The inner surface 50re, 50le and the side wall portions 25r, 25l are not in contact with each other so as to be slidable with respect to the outer surface of the inner surface 25l.

  Therefore, when the tray 20 is accommodated in the main body 10, the side walls 25r and 25l of the tray 20 are sandwiched between the inner ends 50re and 50le of the pair of guides 50r and 50l, and the tray 20 is moved inward. It is possible to slide in the front-rear direction as guided by the ends 50re and 50le. That is, in the operation of taking the tray 20 in and out of the main body 10 in a narrow space such as a cage, the sliding direction of the tray 20 is inclined, and the rear side of the tray 20 is mainly caught by the main body 10. Is suppressed. Thereby, in the animal litter box 3 composed of the two members of the main body 10 and the tray 20, the tray 20 can be taken in and out more stably.

  In the animal litter box 3, the shape of the tray 20 may be changed as follows. 14A and 14B are schematic cross-sectional views illustrating a modified example of the animal litter box 3.

  In the example of FIG. 14A, guide receiving portions 55r and 55l are formed at the upper end portions of the side wall portions 25r and 25l of the tray 20. The guide receiving portions 55r and 55l are portions provided so as to protrude outward in the left-right direction from the upper ends of the side wall portions 25r and 25l, respectively. When the tray 20 is stored in the main body 10, the lower surfaces of the guide receiving portions 55r and 55l of the tray 20 are slidably contacted with the upper surfaces of the guide portions 50r and 50l of the main body 10, respectively. In this modified example, the tray 20 can slide in the front-rear direction while being supported in the up-down direction by the guide portions 50r and 50l. Thereby, the slide movement of the tray 20 can be performed more stably.

  On the other hand, in the example of FIG. 14B, grooves 56r and 56l corresponding to the shapes of the guides 50r and 50l are provided on the outer surfaces of the side walls 25r and 25l of the tray 20 in the left-right direction. As shown in FIG. 14B, the guide portions 50r and 50l are loosely fitted in the grooves 56r and 56l, respectively, so that the tray 20 can be easily slid along the guide portions 50r and 50l. Further, in the present modified example, since the movement of the tray 20 in the front-rear direction is regulated by the grooves 56r, 56l and the guides 50r, 50l, the sliding movement of the tray 20 can be performed more stably.

  In the example of FIGS. 14A and 14B, at least the tray 20 is supported from the lower side in the vertical direction to the upper side by the guide portions 50r and 50l, so that the plane on which the animal litter box 3 is placed (for example, a floor or the like). The base of the tray 20 does not have to be grounded to the table). That is, since the tray 20 can be slid while being floated from a flat surface, the frictional force generated when the tray 20 is slid is reduced, and the tray 20 can be easily taken in and out.
